Date and race-format check
The marathon is on November 7, 2026, at 8:30 a.m. from the marina at Lake Chabot Regional Park, 17600 Lake Chabot Road. The route runs around the reservoir and surrounding hills; prepare for trail footing and elevation rather than steady road splits. The same event also offers 8K, half marathon, 30K and 50K distances, so check the marathon course markings and instructions specifically.
Course + conditions (what should change in training)
- Surface: Terrain.
Course pacing signals (what to rehearse)
- Mixed surface: practice transitions (grip, cadence, downhills) so race day feels familiar.
- Course profile unknown: verify elevation/profile before setting pacing targets.
- Crowds/wind rule: treat headwinds and congestion as “hills” and stay effort-controlled.
